OVERVIEW

Project overview

Our client, a team of professional sports card traders in the United States, needed accurate pricing information across multiple online marketplaces. Their business depended on identifying undervalued cards and responding quickly to changing listings, bids, and sales.

VARTEQ's team developed a custom market intelligence platform that combines automated marketplace data collection, historical pricing records, and an API for accessing market information through the client's existing tools.

WHERE THEY STARTED

The challenge

The client relied on manual research to track sports card prices across eBay, Facebook Marketplace, and specialized trading forums. With listings changing frequently and auctions ending throughout the day, their existing process made it difficult to evaluate cards accurately and act on potential opportunities.

Fragmented marketplace data

Pricing, bidding, and sales information was spread across different platforms, with no centralized system for monitoring market activity.

Outdated pricing information

Expired listings, removed auctions, and changing bids affected data accuracy. Manual tracking couldn't keep pace with marketplace updates.

Limited historical visibility

Traders needed access to historical pricing trends alongside current listings to evaluate card values and identify market patterns.

WHAT WE BUILT

The solution

  1. Automated marketplace data collection

    Custom data scrapers that collect sports card listings, bidding activity, and sales information across eBay, Facebook Marketplace, and specialized trading forums.

    • Built and tested scrapers for the selected marketplaces
    • Collected listing, bidding, and sales data
    • Focused on high-interest categories, including basketball and baseball cards
    • Optimized data collection for timely updates and accuracy

  2. Historical pricing database

    A structured database that maintains historical listing and pricing information, giving traders more context for evaluating current market activity.

    • Stored historical pricing records
    • Organized market data across supported card categories
    • Supported analysis of pricing patterns and trends
    • Made historical records available alongside current marketplace data

  3. Market intelligence API

    A custom API that makes pricing evaluations and market trend information accessible through the client's existing dashboards and trading tools.

    • Delivered current pricing information through API endpoints
    • Supported access to historical market trends
    • Connected collected marketplace data with the client's existing workflows
    • Included API documentation to support integration

  4. Platform optimization and deployment

    Development and deployment work focused on data accuracy, processing speed, and integration with the client's trading operations.

    • Tested marketplace scrapers before deployment
    • Optimized data collection and processing
    • Worked with the client to validate trading requirements
    • Delivered the platform within a three-month development period
